  12. Elektronische Zigarette nach Anspruch 1, dadurch gekennzeichnet, dass der Zylinder (610) ein Heizzylinder ist, auf dessen einem Ende ein Ende des Lufteinlasskanals (620) aufgesetzt ist, wobei in der Seitenwand des Lufteinlasskanals (620) ein Durchgangsloch (620a) ausgebildet ist, wobei das Temperaturerfassungsende (631) durch das Durchgangsloch (620a) hindurch in den Lufteinlasskanal (620) hineinragt und in der Nähe des Heizzylinders angeordnet ist.
  13. Elektronische Zigarette nach Anspruch 12, dadurch gekennzeichnet, dass der Lufteinlasskanal (620) einen ersten Kanal (621) und einen zweiten Kanal (622) umfasst, welcher erster Kanal (621) und welcher zweiter Kanal (622) in einem voreingestellten Winkel zueinander angeordnet sind, wobei der erste Kanal (621) auf einem Ende des Zylinders (610) aufgesetzt ist, während ein Ende des zweiten Kanals (622) an dem anderen Ende des ersten Kanals (621) angeordnet und mit dem ersten Kanal (621) verbunden ist, wobei das Durchgangsloch (620a) in der Seitenwand des ersten Kanals (621) ausgebildet ist, oder dass der Lufteinlasskanal (620) einen ersten Kanal (621) und einen zweiten Kanal (622) umfasst, welcher erster Kanal (621) und welcher zweiter Kanal (622) in einem voreingestellten Winkel zueinander angeordnet sind, wobei der erste Kanal (621) auf einem Ende des Zylinders (610) aufgesetzt ist, während ein Ende des zweiten Kanals (622) an dem anderen Ende des ersten Kanals (621) angeordnet und mit dem ersten Kanal (621) verbunden ist, wobei das Durchgangsloch (620a) in der Seitenwand des zweiten Kanals (622) ausgebildet ist.
  14. Verfahren zum Erfassen die Anzahl an einer elektronischen Zigarette gemachter Züge, umfassend Folgendes:
    - Bestromen eines Zigarettenkörpers zum Vorwärmen der innerhalb des Zigarettenkörpers vorhandenen Luft, bis die Temperatur innerhalb des Zigarettenkörpers einen voreingestellten Temperaturwert erreicht,
    - bei Nicht-Ziehen an der Zigarette von einem Temperaturerfassungsende eines Temperaturerfassungselements ein erster Temperaturwert erfasst wird,
    - beim Ziehen an der Zigarette die Außenluft über eine Lufteinlassöffnung durch einen Lufteinlasskanal in einen Zylinder eintritt, so dass ein innerhalb des Luftstromkanals fließender Luftstrom entsteht, wobei beim Vorbeiströmen des Luftstroms an dem Temperaturerfassungsende des Temperaturerfassungselements von dem Temperaturerfassungsende ein zweiter Temperaturwert erfasst wird, wobei zwischen dem zweiten Temperaturwert und dem ersten Temperaturwert eine Temperaturdifferenz besteht, und
    - durch eine Platine die Temperaturdifferenz zwischen dem ersten Temperaturwert und dem zweiten Temperaturwert, welche von dem Temperaturerfassungselement erfasst wurden, empfangen, diese Temperaturdifferenz in ein induktives Signal umgewandelt und durch Erfassen des induktiven Signals die Anzahl der gemachten Züge ermittelt wird.
  15. Verfahren nach Anspruch 14, dadurch gekennzeichnet, dass der erste Temperaturwert niedriger als der zweite Temperaturwert ist, oder dass der erste Temperaturwert höher als der zweite Temperaturwert ist.
  16. Verfahren nach Anspruch 14, dadurch gekennzeichnet, dass das Bestromen des Zigarettenkörpers zum Vorwärmen der innerhalb des Zigarettenkörpers vorhandenen Luft, bis die Temperatur innerhalb des Zigarettenkörpers einen voreingestellten Temperaturwert erreicht, das Bestromen einer Heizbaugruppe umfasst, die im bestromten Zustand Wärme erzeugt, mit der die die Heizbaugruppe umgebende Luft vorgewärmt wird, oder dass das Bestromen des Zigarettenkörpers zum Vorwärmen der innerhalb des Zigarettenkörpers vorhandenen Luft, bis die Temperatur innerhalb des Zigarettenkörpers einen voreingestellten Temperaturwert erreicht, das Bestromen eines Zylinders umfasst, der im bestromten Zustand ein in einer Aufnahmekammer abgelagertes Tabakprodukt durch Wärmeleitung unmittelbar erwärmt.
